Vampires

Vampires are beings in folk belief and mythology, afflicted with a supernatural virus that drives them to drink blood from other beings, often using fangs to inflict wounds from which to obtain it. Vampires are often (but not exclusively) portrayed as undead and possessing immortality, heightened senses, and supernatural powers of strength, speed, and mind control.

The appearance of vampires in the various TMNT universes have been a semi-common occurrence over the years.

In Volume 4, Raphael is attacked and bitten by a gang that turned out to be a group of vampires; although Raphael did not turn into a vampire the vampirism mixes with the mutagen in his system and causes him to transform into an initially uncontrollable dinosaur-like beast. After Raphael manages to control his monstrous side, he succeeds, together with Casey, in capturing those vampires who were responsible for his monstrous transformation.
